[911 tweaks]

I am in need of info on what I have here.

1. I am told this is a 79' 3.0 SC engine, *6591617*, true??

2. Type # 930/06

3. Top center of case halves both have # 887 = both case havles match.

4. ****** 2 silver round discs either rivited into case or threaded in say,
"GUARANTEE VOID IF REMOVED"...What does this mean??

5. **** a number is stamped under the Red paint, almost at the case seam,
between the 2 silver discs and the number under the paint is 2 0 . What does this mean??

I hope I didnt buy a boat anchor...any and all help is much appreciated!!!
